on mounting the rear plate and inserting the module into the frame see the 7700FR chapter section 3.
Figure 2: Rear Panel
2.1. VIDEO CONNECTIONS
FILL Input BNC connector for 10-bit serial digital fill signals compatible with the SMPTE 259M
standard. The module needs to be set to a specific video input standard using the on screen
menu at this current time. See Table 5 for a list of the video standards supported.
KEY Input BNC connector for 10-bit serial digital key signals compatible with the SMPTE 259M
standard. The module needs to be set to a specific video input standard using the on screen
menu at this current time. See Table 5 for a list of the video standards supported.
FILL OUTPUTThis BNC connector is used to output the converted input fill signal as serial component
video, compatible with the SMPTE 292M standard and has on screen display menus (OSD)
superimposed over the video The module needs to be set to a specific video output standard
using the on screen menu at this time.

7700 MultiFrame Manual

Revision 0.2 7710UC-KF-3
KEY OUTPUTThis BNC connector is used to output the converted input video as serial component video
compatible with the SMPTE 292M standard. The module needs to be set to a specific video
output standard using the on screen menu at this time.
Note: The Fill and Key Inputs must be of the same video standard, and the Fill and Key
Outputs must also be of the same video standard.
2.2. GENLOCK REFERENCE
For proper synchronization of the output video, the Key/Fill Up Converter must be locked to a genlock
signal of the output video format.
GENLOCK This BNC is for connecting a bi-level or tri-level sync reference and is auto-detected by the
module. Jumper J21 selects whether the reference input is terminated to 75 ohms or high
impedance (default). (See section 7.3). The Reference menu item is used to select the correct
type of video reference being used. The output video can be timed with respect to the genlock
video using the H Phase Offset and V Phase Offset menu items. (See section 6.3.1) When no
Genlock is provided, the output video is timed with respect to the input video.
2.3. GENERAL PURPOSE INPUTS AND OUTPUTS
On the 7710UC-KF a 6 pin connector labelled AUX I/O contains 4 GPI/O inputs. The connector pinout is
shown Figure 2. See section 7.4 for information about configuring the GPIO configuration.

6.1. NAGIVATING THE ON SCREEN MENU SYSTEM
A toggle switch and pushbutton allow card edge navigation of a set of on-screen menus used to configure
the card. To enter the on-screen menu system press the pushbutton. This will bring you to the main
Setup menu where you can use the toggle switch to move up and down the list of available sub menus.
An arrow (Î) moves up and down the left hand side of the menu items to indicate which item you are
currently choosing. Once the arrow is on the desired item, press the pushbutton to select the next menu
level.
On all menus, there are two extra selectable items: Back and Exit. Selecting Back will take you to the
previous menu (the one that was used to get into the current menu) while Exit will return the display to its
normal operating mode. On the main menu, BACK and EXIT will both take you to the normal operating
mode.
Once in a sub menu, there may be another menu layer, or there may be a list of parameters to adjust. If
there is another set of menu choices, use the toggle switch to select the desired menu item and press the
pushbutton.
To adjust any parameter, use the toggle switch to move up or down to the desired parameter and press
the pushbutton. The arrow will move to the right hand side of the line (Í) indicating that you can now
adjust the parameter. Using the toggle switch, adjust the parameter to its desired value. If the parameter
is a numerical value, the number will increase if you lift the toggle switch and decrease if you push down
on the toggle switch.
When you have stopped at the desired value, depress the pushbutton. This will update the parameter to
the selected value and move the arrow back to the left side of the parameter list (Î). Continue selecting
and adjusting other parameters or use the BACK or EXIT commands.

6.3.6. Setting up the Video Output Timing
The output stage of the Key and Fill Up Converter contains a frame buffer so that the output video can be
timed with respect to the reference applied to the GENLOCK input when the Reference Select menu item
is set to External. In the absence of a genlock signal, or when the Reference Select menu item is set to
Video the output video will be timed with respect to the incoming Video.
!
The V Phase Offset and H Phase Offset adjustments are REAL TIME
ADJUSTMENTS and will affect the output video timing immediately. These
settings should not be adjusted when the output video is in the broadcast chain.
6.3.6.1. Selecting the Video Reference Source
Video
Reference Select
Video
External
With this control the reference source of video locking is set.
Select External to lock the output video to the reference video applied to the
GENLOCK BNC. If the genlock reference disappears or is not valid, the
card will lock to incoming video.
Select Video to will lock the output video to the input video. When there is
no input video the output video will free run.
6.3.6.2. Calculating the Delay through the Key/Fill Up Converter.
The delay through the Key/Fill Up Converter is dependent on the video input format, the Key and Fill Up
Converter processing mode and the V Phase Offset and H Phase Offset settings. There are separate
settings of H and V phase offset for each output video type. Table 6 shows the default and maximum and
minimum delays for each video standard.
"The delay is counted in the lines and pixels of the output standard and is
calculated from input field 0 start to output field 0 start.

There are separate settings of V phase offset for each output video type.
Setting this control to 0 keeps the output video in time with the Genlock
reference or incoming video if genlock is missing.
Increasing the value will delay the output video in one-line increments of the
output video standard. In order to advance the vertical timing of the output
video with respect to the genlock video, set the control to the maximum total
number of lines of the output video minus the number of lines that you wish
to advance the output video. (E.g. for 1080i/59.94 output video the total
number of lines is 1125, so to advance the output video 5 lines set the value
to 1120.) When increasing the V Phase Offset value causes it to go beyond
the limit of the frame buffer, the V Phase Offset will wrap to the beginning of
the frame buffer, resulting in a change of one frame of throughput delay
between the SD input and the video output. See Table 6 for the minimum
and maximum delays possible.

With this control, you can set the horizontal timing of the output video with
respect to the reference input set by the Reference Select menu item.
There are separate settings of V phase offset for each input video type.
Setting this control to 0 keeps the output video in time with the Genlock
reference.
Increasing the value will delay the output video in one-sample increments.
In order to advance the horizontal timing of the output video with respect to
the genlock video, set the control to the maximum number of samples per
line for the output video standard minus the number of samples that you
wish to advance the output video. (E.g. for 1080i/59.94 output video the
total number of samples per line is 2200, so to advance the output video 5
samples set the value to 2195.) See Table 6 for the minimum and
maximum delays possible.

6.4. CONFIGURING THE SCALER
The Key/Fill Up Converter scaler uses a process of filtering in order to increase or reduce the resolution
during up conversion. The Scaler menus are used to configure the cut-off frequencies of the filters
associated with the scaler hardware. The chart below shows the items available in the Scaler menu.
Sections 6.4.1 to 6.4.5 give detailed information about the menu items.
H Filter Cutoff Sets the type of the horizontal filter in the scaler
V Filter Cutoff Sets the type of the vertical filter in the scaler
H Rate Limit Enable a rate limit on the horizontal edges.
V Rate Limit Enable a rate limit on the vertical edges.
ARC Selects the aspect ratio conversion to be performed
Panel Colors Red Sets the color of the letterbox panels.
Panel Colors Green Sets the color of the letterbox panels.
Panel Colors Blue Sets the color of the letterbox panels.
Input H Start Sets the left side crop position for custom aspect ratios
Input H Stop Sets the right side crop position for custom aspect ratios
Input V Start Sets the top crop position for custom aspect ratios
Input V Stop Sets the bottom crop position for custom aspect ratios
Output H Start Sets the left side of the output image for custom aspect ratios
Output H Stop Sets the right side of the output image for custom aspect ratios
Output V Start Sets the top of the output image for custom aspect ratios
Output V Stop Sets the bottom of the output image for custom aspect ratios

6.4.1. Setting the Scaler Filter Sharpness
There are two controls that adjust the horizontal and vertical filters for the scaler. For the sake of clarity
only the menu item for the horizontal filter control is shown in the manual.
Scaler
H Filter Cutoff
Auto
1 to 64
With this control, you can set the cutoff frequency of the horizontal filter. Set
to either Auto or select 1 of 64 filters 1 thru 64, which are full bandwidth to
1/64th the bandwidth of the input signal.
Scaler
V Filter Cutoff
Auto
1 to 64
With this control, you can set the cutoff frequency of the horizontal filter.
Set to either Auto or select 1 of 64 filters 1 thru 64, which are full bandwidth
to 1/64th the bandwidth of the input signal.
6.4.2. Setting The Rate Limit Contols
There are two controls that adjust the horizontal and vertical rate limit pre-processors for the scaler. Some
video content has excessive edge rates that do not conform to bandwidth limits so these control will apply
a rate limit to edges it detects exceed the normal bandwidth so that the scaling filters will not ring
excessively.
Scaler
H Rate Limit
Disable
Enable
With this control, you can enable or disable the horizontal rate limit function.
Scaler
V Rate Limit
Disable
Enable
With this control, you can enable or disable the vertical rate limit function.

6.4.3. Setting the Aspect Ratio of the Output Picture
The Aspect Ratio menu presets the user image conversion parameter to build it presets. Once selected
the user can fine adjust the picture parameters via the input and output H and V stop and stop menus.
Note: In order to save any modified state as a preset the Aspect Ratio needs to be set to User Aspect.

Full Raster - converts the full input raster to full output raster.
If the input and output aspect ratios are not equivalent there
will be aspect distortion.
User Aspect – converts the region of the input raster defined
by the Input H & V Start and Stop values to the region of the
output raster defined by the Output H & V Start and Stop
values with coloured side panels.
These settings convert the input picture to 16:9 top and
bottom cuts.
These settings squeeze common stretched input video back
to 4:3 side panel images on a 16:9 aspect raster.
These settings are common up converter settings for
converting 4:3 aspect ratio images to common 16:9 formats.
6.4.4. Set the Colour of the Letterbox Panels.
There are three menu items used to set the panel colour. The menu item for each colour component
works in the same way so for simplicity only the menu item for the Red component will be shown in the
manual.
Scaler
Panel Colour Red
0 to 255
This control defines one of the component colours for the colour of the side
panels. Set the R, G or B value for the side panel colour that you want.
Hint you can use a standard colour picker such as is available in Microsoft
Paint to determine the colour values that you want to use.

6.4.5. User aspect ratio setting.
There are four registers for each input video standard that set the portion of the input picture that will be
converted. These register settings do not have any effect when the pre-defined aspect ratios are used.
Scaler
Input H Start
Input H Stop
The Input H Start and Input H Stop define the horizontal portion of the input
image to process to the output
Scaler
Input V Start
Input V Stop
The Input V Start and Input V Stop define the vertical portion of the input
image to process to the output
There are four registers for each output video standard that define the size of the output image and how to
place the resulting image on the output video raster.
Scaler
Output H Start
Output H Stop
The Output H Start and Output H Stop define how to scale the cropped
input image horizontally and where to place it horizontally on the output
raster. The image will be stretched to fill the width. The range of values
for 1080i output is 0 to 1919. The range of values for 720p output is 0 to
1279.
Scaler
Output V Start
Output V Stop
The Output V Start and Output V Stop define how to scale the cropped
input image vertically and where to place it vertically on the output raster.
The image will be stretched to fill the height. The range of values for
1080i output is 0 to 1079. The range of values for 720p output is 0 to
719.
6.5. CONFIGURING THE VIDEO PROCESSING FUNCTIONS
The Video Proc menus are used to configure parameters associated with the video processing functions
of the key and fill up converter. The chart below shows the items available in the Video Proc menu.
Sections 6.5.1 to 0 give detailed information about each of the menu items.
"ALL of these parameters affect the video in real time. H&V frequency bands will
cause hits to the video while a new filter is loaded.
